Carrier 38SYG042 Ignition Control Board
An ignition control board regulates the main gas intake valve, the ignition timing as well as other safety devices. It is an important safety device that is usually a major component of the main board for the sake of being more efficient.
What are the clues to watch out for to know my ignition board is almost dead?
- Everything else in the system is inspected and turns out to be okay
- The electrical signal from the main thermostat never makes contact with the main board
- The primary ignition sequence refuses to fire up at all
